One of the greatest mediators of risks to an infant with a myelomeningocele is:
Respiratory depression.
Decreased cardiac output.
Infection.
Neurological damage.
The Correct Answer is C
Choice A rationale
Respiratory depression is less common in myelomeningocele unless secondary to severe neurological anomalies. It is not the primary risk mediator in this congenital condition.
Choice B rationale
Decreased cardiac output is not directly associated with myelomeningocele. This condition primarily affects the spinal cord and surrounding tissues rather than cardiovascular function.
Choice C rationale
Infection risk is high due to exposed neural tissue, making it the most significant concern. Infection can lead to meningitis, sepsis, and neurological deterioration if not properly managed.
Choice D rationale
Neurological damage is inherent to myelomeningocele but does not act as an external risk mediator. The focus is on preventing additional risks like infections to improve outcomes.

Correct Answer is B
Explanation
Choice A rationale
Surgical intervention is a secondary measure for obstetric hemorrhage and is considered only after initial non-invasive interventions fail to control bleeding, such as fundal massage and uterotonic medications.
Choice B rationale
Fundal massage is the first-line intervention for uterine atony as it stimulates uterine contractions, reducing blood loss by compressing blood vessels at the placental site and promoting hemostasis.
Choice C rationale
Establishing venous access is essential for fluid resuscitation and medication administration but is not the immediate priority compared to fundal massage for controlling active bleeding.
Choice D rationale
Catheterizing the bladder may help assess urinary output and prevent bladder distension, which can impede uterine contraction, but it is not the initial intervention for hemorrhage.
Correct Answer is C
Explanation
Choice A rationale
Retained placental fragments lead to delayed, not immediate, postpartum hemorrhage as they prevent complete uterine contraction over time.
Choice B rationale
Vaginal hematomas cause concealed, localized bleeding with minimal external blood loss, differing from profuse hemorrhage presentations.
Choice C rationale
Uterine atony, the most common cause, occurs when the uterus fails to contract effectively, leading to uncontrolled and excessive bleeding.
Choice D rationale
Uterine inversion, though serious, is rare and typically accompanied by visible uterine prolapse, not commonly causing profuse bleeding in the immediate postbirth period.
